first forced verticallyrdownw'ard through a length of the earth material being'drilled through, whereby thesame is loosened. The drill is then raised `from the hole, and a l hailing tool, comprising means for removing the material loosened hy the drill hit, yis lowered in the hole.' e'

Ordinary hailing tools include a bucket,

into which the loosenedmaterial is forced through a relatively small aperture in the bucket bottom. e' Y i Y Y In drilling a hole through certain kinds'of relatively hard material, the walls of the 'Y hole will remain in Vplace after the loosened ing, and improved means facilitatingv the o material is hailed therefrom.` j

In drilling through certain classes of relatively soft or easily crumbledmaterial, the walls of the drilled yhole often cavein,and block the hole with lumps and loosened vmaterial known as cavings. I l

These cavings may Vcomprisevery large lumps which it is necessary to break up withV a drill hit; and, in the use of .a drillA hit, water is required to` make a mud from the' drillings so that the drill `will function properly. e The ordinary drill hit will workv intoA cavf' ings from 4 to 6 feet, but when pulled'out of the mud madehy the waterused as aforefv said, the undrilled cavings will immediately fall on topv of the mud 'which was washed down by the action of the drill stem and the water, and such pieces `of undrilled cavings are too large to enter the .usualhailer with a relatively small opening.

ln such Vcases when suche Ycavings f are reached it i'sneces'sary to run casing through the cavings before further drillingcan he.

In a very deep drill hole, cavings at sev-V eral locations may he encountered before thev e y rial.

oil or the like is reached, andfinsuch cases several Vlengths of casings must `he inserted. On theother hand if caving material is removed in a dry state there is no tendency ytofurther enlarge the cave pocket.

Accordingly, the"ohjectsV of the present improvements include the provision of a hailing tool which will eliminate thefnecessity of running casings andV of under-reaming, in order to drill through caving mate- These and ancillary objects are attained in the improved hailing tool, hereinafter set forth in detail, and claimed, andwhich mayr be stated in general,` terms .,aspincluding a bucket, an opening at Vthelower end of the bucket having an area very slightly less than the full crosssectional area of the hole being drilled, an automatic `closuresfor said open-V removal of material collectedin the bucket.

A preferredv embodiment-of the improve- Y ments is illustrated in the accompanying drawings forming part hereof, in which Figure 1 is a fragmentary view with portions in section, illustratingithe improved hailing tool hereof in'use in ya drill hole; Fig.v vi2, an enlarged longitudinal axial sec tijenal view of the improved hailing tool here-- o i I Fig. 3, an elevationview illustrating Athe key used for emptying the hailing tool; V

Similar numerals refer to similar parte throughout the several views.

The improved bailing tool indicated generally at 10 includes a bucket indicated generally at 11 and the bucket 11 preferably includes a relatively long tubular trepanning drill 12 having walls forming a continuous unobstructed passage-way having a uniform cross-section from end to end thereof, and an improved automatic closure 13 located within the tubular drill 12 a suitable distance above the preferably ground angled peripheral cutting edge 14 thereof.

The closure 13 has preferably a downwardly concave oval spoon shape, and is pivotally mounted at its lower end as at 1.5 upon a substantially semi-cylindrical side gate 16, which is pivotally mounted at its upper ends as at 17 upon the outside of the tubular drill 12. A suitably shaped openingl 1S is provided in the side wall of the tubular drill 12 intermediate and spaced from the ends of the drill,

Vwhich opening 1S is normally covered by the side gate 16, and the spoon shaped closure 13 may extend from its pivotal mounting on the side gate 1G through the opening 13.

The continuous unobstructed passage-way vthrough the tubular drill 12 preferably has an enlargement 19 intermediate and spaced from the ends of the drill 12, adjacent and communicating with the opening 18. rlhe pivot 15 of the closure 13 is located adjacent vthe enlargement 19 so that the closure 13 is mount-ed for movement within the enlargemeut; and the enlargement forms a suitably shaped upwardly angled ledge seat 20 at the intersection of the enlargement and the passage-way upon which seat the outer edge 21 of the downwardly concave oral spoon shaped closure 13 may seat, for closing the lower end of the bucket.

As best illustrated in Fig. 2, the spoon closure 13 is provided preferably with an inwardly extending upper tip 22 which is spaced at a distance from the upper edge 23 of the opening 18 for a purpose which will hereinafter be set forth in detail.

Externally, the tubular drill 12, has formed therein a suitable recessed seat in the outer surface of the tubular member surrounding the opening 18 indicated generally at 24 for v the seini-cylindric side gate 1G, whereby when illustrated in Fig. 2, which is the normal position for hailing operations, the side gate 16 is provided in its lower end with an improved key operated latch 27 which includes a head 23 mounted for rotation in a suitable bearing 29 formed at the lower end olf the side gate, and which head has secured upon its inner end, a locking segment 30, adapted in one position for passing through a segmental opening 31 in the tubular drill 12, and when rotated, for end engagement with suitable flanges forming the sides of the segmental opening.

As illustrated the inner sur'a ce ot the locking segment 30 preferably conforms with the inner surface of the tubular drill 12, and the outer curved ends 33 of the segment 30 are iabbeted and the flanges 32 are rabbeted for inner engagement with each other as at 311-, and the i'abbeted surfaces may be angled for providing a clamping engagement between the segment 30 and the tubular drill 12, whereby the si de gate 1G may be secured in the position illustrated in Fig. 2.

'he latch 27 is arranged to be rotated as by means of a key 35 which includes a handle 3G mounted at one end of a shaft 37, at the other end of which laterally extending wings 33 are secured.

rlhe rotatable head 23 of the latch 27 is provided vitli a suitably shaped key hole 39 ari' iiged to receive the shaft and wings of the key 35, and the segment 30 of the latch is provided with an enlarged sectoral aperture Ll() permitting sutlicient rotation of the key 35 to provide an engagement between the inner ends Ll1 of the wings and the inner face L12 of the head 23, whereby the key 35 may serve as a handle for opening the side gate 16.

For normally maintaining the rotary latch 27 in any desired position, but permitting automatic ope-ration of the saine by the use of the key 35, the beari 2f) for tiie latch head 23 is provided with a. plurality of inwardly opening laterally extending "-l' notches 'l-3 into which the wedge ends l-lof spring pressed bolts carried in the head may extend; the pressure of the springs e6 for the spring pressed bolts l5, and the wedge and notch angles being such, as to permit rotation of the latch by the key but to prerent rotation of the latch during the normal use of the tool.

ln Fig. 1, a drill hole is indicated at 417, in which a cave-in of the side walls has occurred forming a cave pocket in which eavings 49 are contained.

rl'he improved hailing tool 1() is secured as by means of a collar 50 at the lower end of pipe 51. the diameter of the particular tubular drill 12 for the hailing tool being` substantially equal to the dian'ieter of the drill hole, and the tubular wall of the drill 12, being only of sutiicient thickness to secure the proper strength, the opening through the drill haring a cross-sectional area, only slightly Y pipe may be provided at its upper end as il less than the cross-sectional area of the drill hole.

The'upper end of the pipe 51 is secured as by a coupling 52 with a relativelyshort connecting pipe 53 "which is preferably provided withV side holes 54; through whichexcess material may escape. The connecting Vtothe position illustrated in full lines in Fig. 2 within the enlargement 19 permitting free passage ofthe Ycavings along the passageway formed by the drill walls 12.y Asthe tool trepans through the cavings, and the cavings enter upwardly into the pipe '51, when the tool is raised, the closure automatically swings to the position illustrated in dash and dot lines in Fig. 2 within Vithe ,enlargement entirely closing off the continuous passage-Way 12, thereby trapping cav-ings in the bucketI thus formed, and the inturned upper end 22 of the spoon closure, insuring that the closure will. drop into place without the useof any springs.

After the pipe 21 has been illed with cavings thus collected,'the tool is thenraised from the hole, andthe key is used to swing back the side gate 16. rIhe bailing tool having been swung away from ,the entrance to the drill hole, to a suitable dump, the Vside gate isfswung raway from its normal position as illustrated in Fig. 4 for withdrawing the closure member 13 from the enlargement 19 through the Vside wall opening A18, and the bucket will' empty itself.

In one drill hole therewere 10 feet of cavings, which were drilled and bailed in theold manner for 150 hours without making the hole a foot deeper. Y Y

The tool vof the present invention was used as aforesaid, and all theO feet of cavings were removed in three hours time without running a drill stem or Without'setting any Casing,.andafter the cavings were removed,

the `hole was drilled in the usual manner until oil sand was struck.
